This paper derives the conditions to be satisfied by the amplifier in each stage of a multistage amplifier in order for it to be absolutely stable. It is shown that the stability factor K of each stage need not be larger than unity except for the ini

Most power amplifiers with several FETs in parallel utilize a two-way power dividing/combining circuit of asymmetric structure. The asymmetric structure provides unequal power dividing/combining characteristics. In this paper the power dividing/combi

Proceedings of IEEE Antennas and Propagation Society International Symposium and URSI National Radio Science Meeting.
In mobile satellite communication systems such as the AMSC/TMI system [Lunsford et al., 1992], circularly polarized omni-directional antennas are attractive for vehicle antennas because any satellite tracking mechanism in the azimuth direction is not
